Royal fern (mazein) ideas?

Hello everybody! I just got this bag of royal fern strips, cause I was at this Korean grocery and thought it looked interesting... I mean, come on, they're so pretty as house plants. Hem, I guess the idea of eating some just caught my fancy. However, I don't know what to do with them. I tried eating them raw, but that was honestly kind of gross. Anyone ever heard of or used them? Thanks.
